No, it happened after a period of inactivity, when I switched it on to load 12.0 it was suddenly acting crazy. I cannot recall any activity that would have impacted on the unit, just working on engine and airframe related stuff mostly, not Skyview stuff. I loaded 12.0 hoping somehow it would make a difference, it did not. The autopilot also seems crazy when turned on, I suspect it is trying to get out of the unusual attitude or something. A red light is blinking on the unit as well, had never noticed that before.
